Variable Induction Control Solenoid: Testing and Inspection

VSV FOR T-VIS INSPECTION
1. DISCONNECT AND REMOVE THE VSV FROM THE ENGINE.
- Disconnect the following connector and hoses:



(1) VSV connector.
(2) Vacuum hose (from T-VIS valve) from port E of VSV.
(3) Vacuum hose (from vacuum tank) from port F of VSV.
- Remove the screw, bolt and VSV.

2. INSPECT VSV FOR OPEN CIRCUIT.



- Using an ohmmeter, check the resistance between the terminals.

Resistance (COLD): 33 - 39 ohms

- If terminal resistance is not as specified, replace the VSV.

3. INSPECT VSV FOR SHORT CIRCUIT.



- Check for continuity between the case and either terminal.
- If windings are grounded to case replace the VSV.

4. INSPECT VSV OPERATION.



- Blow through pipe E and check that air flows through pipe E and out the filter.




- Apply battery current to the VSV and check that air flows through pipe E to pipe F.

- If a problem is found, replace the VSV.

5. RE-INSTALL VSV ON THE ENGINE AND RECONNECT VACUUM HOSES.
- Install the VSV with the bolt and screw.
- Connect the following connector and hoses:



(1) VSV connector.
(2) Vacuum hose (from T-VIS valve) to port E of VSV.
(3) Vacuum hose (from vacuum tank) to port F of VSV.
